Patch generation is an essential software maintenance task because most software systems
inevitably have bugs that need to be fixed. Unfortunately, human resources are often …

Debugging consumes significant time and effort in any major software development project.
Moreover, even after the root cause of a bug is identified, fixing the bug is non-trivial. Given …

Software bugs remain a compelling problem. Automated program repair is a promising
approach for reducing cost, and many methods have recently demonstrated positive results …

The abundance of defects in existing software systems is unsustainable. Addressing them is
a dominant cost of software maintenance, which in turn dominates the life cycle cost of a …

Software performance is critical for how users perceive the quality of software products.
Performance bugs-programming errors that cause significant performance degradation-lead …

Many bugs, even those that are known and documented in bug reports, remain in mature
software for a long time due to the lack of the development resources to fix them. We …

Many techniques on automated fault localization (AFL) have been introduced to assist
developers in debugging. Prior studies evaluate the localization technique from the …

Most techniques for automated program repair use test cases to validate the effectiveness of
the produced patches. The validation process can be time-consuming especially when the …

This paper presents a novel methodology for localizing faults in code as it evolves. Our
insight is that the essence of failure-inducing edits made by the developer can be captured …

Many of the problems posed by the migration of computation to cloud platforms can be
formulated and solved using techniques associated with Search Based Software …
